Extrusion-sealed structure of heat pipe

Abstract

An extrusion sealed structure of a heat pipe. A heat pipe that has been extrusion-sealed includes a circular tubular body with two free ends connected to conical shrunk tubular portions. One end of each shrunk tubular portions is connected to the circular tubular body, and the other end of the shrunk tubular portion has one side surface extruded into a recessed portion and the other side surface retains the shape of the circuit tubular body and the shrunk tubular portion. The sealing portion is located at a central axis of the tubular body.

1. An extrusion sealed structure of a heat pipe, including a tubular body having two free ends connected to respective conical shrunk tubular portions, wherein a joint between the tubular body and conical shrunk tubular portions has one side surface pressed into a recessed portion and the other side surface retaining original shape of the tubular body and the conical shrunk tubular portion, such that a sealing portion is formed at a partial circumference of a circle radially outward of a central axis of the tubular body.
